Hydraulic System Care - 2012-11

Hydraulic
Reservoir

Visually inspect the
oil level. The level should be between 1/4 and 3/4 of the sight glass.

With the shelf package
fully lowered the oil level will be at about 1/4 height on the sight glass.

With the shelf package
fully raised the oil level will be at about 3/4 height on the sight glass.

Inspect for any
visible oil around the hydraulic system.

With the shelf package
down test for the proper stoppering pressure.

The proper stoppering pressure can be found in the owner's
manual or your company's SOP.

Every 5 - 7 Years:

Disassemble the
hydraulic power pack

Inspect the high
pressure hose for possible damage.

Thoroughly clean the
reservoir interior.

Clean the metal
suction screen.

Refill with new
hydraulic oil.

Hydraulic
Ram

The vacuum sealing
o-rings for the hydraulic ram need to be serviced every 3 to 5 years. This is
both the ram o-rings and the vacuum flange o-rings if an external vacuum
sealing gland is used.

System
Pressure

The system pressure
should be checked annually. The proper pressure setting is in the documentation
received with the machine.

Shelf
Operation

The downward shelf
operation should be smooth and not chattering. If there is chattering the flow
control valve located near the hydraulic power pack reservoir should be
adjusted. This adjustment and location is explained in the owner’s manual.

These technical tips are for use by qualified maintenance
personnel who are familiar with their specific freeze drying equipment. These
tips are intended only as general guidelines. Lyophilization equipment is
frequently custom configured and some tips may not be appropriate for all
freeze dryers. Always read and follow the directions of your equipment's
maintenance manual. If you would like to discuss one of our tech tips, please
